评估模板规则 xslt 的内部错误

Question

我正在尝试在我的一个服务器中使用 XSLT 组合一组 XML 文件，并收到以下文件集错误（不是所有文件）：

我已经尝试了 xslt 的 document() 和 collection() 方法，它们可以用来合并文件。但得到同样的错误。

主要问题是，这个错误只发生在这个特定的服务器上。当我在本地或其他服务器上运行同一组文件时，它运行没有任何问题。

过程中用到了以下内容：

XSLT 2.0

撒克逊 9.7.0-8

java 1.7.0_95

任何帮助将不胜感激。

它在 Oracle XDK 解析器中严重崩溃（Saxon 只是在传递坏消息）。不幸的是，解析器不是开源的，我怀疑 Oracle 正在监视这个论坛，所以从技术上讲，你应该向 Oracle 提出支持请求。在实践中，最好的方法可能是切换到不同的解析器：JDK 内置的解析器或 Apache Xerces。

我怀疑您使用 XDK 解析器的唯一原因是它恰好位于类路径中，或者存在于“认可的库”目录中。

您可以在使用方法Processor.setConfigurationProperty(FeatureKeys.SOURCE_PARSER_CLASS, className) 调用document() 函数时更改Saxon 使用的解析器。
